Officers Mark Richardson and Adam Laurent were fired following an independent investigation into the November 2009 incident. A video released this year shows Richardson shoving prisoner Michael Bergeron, then 19, headfirst into a wall.

Bergeron can then be seen slumping to the floor. As he's maneuvered down the hall by Richardson, Laurent and Officer Keith Dietenhofer, Laurent can be seen spraying Bergeron with pepper spray, investigators said.

Richardson was charged with assault following a criminal investigation into the incident. The three officers had been placed on paid leave once the investigation began, but Richardson stopped being paid after he was charged.

As a result of the town's investigation, Dietenhofer was given a two-day unpaid suspension, officials said. The supervising officer that evening, John Wasson, wasn't directly involved in the incident, but he was reduced from lieutenant to patrolman for not providing sufficient supervision.

The incident didn't come to light until the video was posted online in January.
